In a significant leap for the maritime and energy sectors, the Chinese mainland has successfully delivered the Puteri Johor, a 174,000-cubic-meter liquefied natural gas (LNG) carrier. This delivery marks a pivotal moment in the industry, as the vessel is the first of its kind to feature a fully domestic set of cryogenic valves within its cargo containment system.
According to reports from China Media Group (CMG), this achievement effectively completes the full domestic supply chain for large LNG carriers. From raw materials and engineering design to specialized equipment, the Chinese mainland now possesses the comprehensive capability to produce these complex vessels independently.
The Puteri Johor was constructed by Hudong-Zhonghua Shipbuilding, a subsidiary of the China State Shipbuilding Corporation (CSSC). The scale of the vessel is immense, measuring 299 meters in length and 46.4 meters in width, with a deck area comparable to three football fields. Its four massive cargo tanks can transport 174,000 cubic meters of LNG—a volume sufficient to power approximately 3.3 million households for an entire month.
For global investors and maritime analysts, this development signals a strategic increase in production efficiency and a reduction in reliance on external components for high-tech shipping. By mastering critical cryogenic valve technology and streamlining construction timelines, China continues to strengthen its position as a leader in global shipbuilding and energy logistics.
